when my car is cold i I begin to drive the brake light comes on only till it warms up any else have this prob, btw i tried using there pressing and releasing parking brake and it still stays on. THAANKS in ADVANCE.

 

first make sure the fluid level is good, then go from there

 

This happened to me when I lived in a cold place... just top up the brake fluid and you will be fine.

 

I had the same issue, the brake fluid level was fine, the light would come on due to water on the sensor in the wheel well. I Removed my wheels, and cleaned the inside and dried out the lines and taped the sensors, no more issues...

Seem to only happen when it rained a lot, especially after the 2 hurricanes we had.

If this doesn't work for you I would take it in and have it checked out.

 

This happened to me and it turned out to be the cap on the master cylinder. There's a sensor/switch in the cap that has a tendency to go belly after a cold snap. The dealer fixed it under warranty.
